Thanks, I missed that. I ran my discharge test with a fan, but it only draw about 35W. So I didn’t reach the max discharge rate.

]]>The FLLEEYPOWER 12V 6Ah LiFePO4 Battery has the specifications listed below. Please note the max continuous discharge current is 1C. In this case that’s 6 Amps. It could handle 12 amps (2C) discharge but for only 3 to 5 seconds. So your statement about running 12amps for 1/2 hour is inaccurate. It could only handle this load for 5 sec max.

To summarize:

1. It will power a load at 6 amps continuous for 1 hr. (~76watts)

2. Or, Power a load of 12 amps for 5 sec (~144watts)
